Weighting For Final Residential Code Analysis • Last issue for residential modeling • Weighting from NEEA regional analysis figures • Adjusted to account for national code climate zones • Salem airport and Redmond airport weather files continue to be used • Spreadsheet will be available for public • Weighted result used for 2006 residential code (100%) • 2030 Target to be 40% of this figure for September report to Governor • Analysis of path to 2030 target beginning 3

Commercial Code Baseline and Progress We have the benefit of several existing studies that can be leveraged to establish the baseline in 2006 and current progress ASHRAE ASHRAE ASHRAE 90.1-2004 90.1-2004 90.1-2004 % Energy Use % 2004 OSSC (2006 code) % ASHRAE 90.1-2016 90.1-2016 Building Performance Factors ASHRAE Table 4.2.1.1 90.1-2019 90.1-2019 Building Performance Factors Table 4.2.1.1 5
Commercial Code Baseline and Progress Use the fixed comparison to ASHRAE 90.1-2004 to establish Oregon 2019 (current) and next-cycle progress compared to Oregon 2006 ASHRAE ASHRAE ASHRAE 90.1-2004 90.1-2004 90.1-2004 % Energy Use 2004 OSSC (2006 code) % = ? ASHRAE % = ? 90.1-2016 EO 20-04 ASHRAE Baseline 90.1-2019 6
Commercial Code Baseline and Progress • From report, 2004 OSSC was ~5% more effici cient than 90.1-2004 for whole building energy use (weighted average across multiple building types in that study) • Adjustments: • Remove “Misc. Electric Loads” from both Oregon and 90.1 - 2004 • Re-weight building types to align with ASHRAE weightings for similar building types • Result: 2004 OSSC was about 4% more effici cient than 90.1-2004 7
